Herein we describe methods to automatically and continuously measure variation in the physical environment and activity of amphibians and reptiles. Data quantifying the relationship between environmental variation and herpetofaunal activity and physiological state (e.g., temperature) can be used to optimize sampling procedures for inventory and monitoring programs and in the interpretation of population changes (Peterson and Dorcas 1992; 1994). Because many factors vary through time, it is often important to sample regularly over hours, days, and even seasons. For example, the environmental temperatures available to an amphibian or reptile may change dramatically over just a few hours and over extended periods of time (Peterson et al. 1993). Automated sampling systems make it possible to measure continuously a wide variety of variables accurately at one or more sites. We discuss how to automatically monitor the environments of herpetofauna using dataloggers, environmental sensors, and physical models and how to automatically monitor animal body temperatures using dataloggers. We also discuss how to automatically monitor movement and activity using automated radiotelemetry, global positioning systems (GPS), passive integrated transponders (PIT) tags, and automated photographic and video techniques. We have included the names of various manufacturers, especially for the equipment and materials that we have used. However, our experience with different types of equipment and techniques is limited and the listing of a particular vendor doesn't indicate our endorsement. Furthermore, the evolution of equipment is proceeding rapidly and many of our specific comments may already be out of date. We have successfully used Thermochron iButtons to measure seasonal body temperature variation and infer activity patterns (e.g., basking) in painted turtles (Chrysemys picta) inhabiting a farm pond in Davidson, NC
